My bigger female has laid three clutches of eggs so far. The first was 8 or so, the second was 11, and yesterday was 14! So far no fertile ones, though I understand that's perfectly common in new egg-layers. There have been one or two double-yolked eggs in each clutch, and similarly some egg cases without yolks.

Is the size of these clutches just a function of her trying to get it all right? Maybe she doesn't know she ought to be laying more frequently with fewer eggs?
